Status: Bogus
Bug Type: Scripting Engine problem
Operating System: Windows Vista
PHP Version: 5.3.0
New Comment:
I disagree with your explanation because $foo['bar'] is never created
as $foo still equals NULL according to my debugger.
And to quote the manual:
"Note: Attempting to access an array key which has not been defined is
the same as accessing any other undefined variable: an E_NOTICE-level
error message will be issued, and the result will be NULL. "
I did RTFM, and it never said anything about trying to access a
variable causing it to be created. The explanation left in the related
bug you referenced is probably more accurate
"Note: Accessing variables of other types using [] or {} silently
returns NULL. "
Even if this is "by design" I still think it should generate a NOTICE,
where could I read about the design decisions of why it was done the way
it was? And would it be appropriate to re-categorize this as a feature
suggestion or do you guys not want to hear about it?

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
RTFM:
http://php.net/count
"There is one exception, if var is NULL, 0 will be returned."
http://php.net/array
"Converting NULL to an array results in an empty array."

Description:
------------
Example A "compiles" and B does not (E_NOTICE).
Invoking an array index on NULL *probably* warrants my attention more
than doing so on an array.
It has cost me countless hours, for one.
Reproduce code:
---------------
// A
$foo = null;
count( $foo['bar'] );
// B
$foo = array();
count( $foo['bar'] );
Expected result:
----------------
2 E_NOTICE errors
Actual result:
--------------
1 E_NOTICE error
